Introduction of Electrodeless Lamp:
High frequency electrodeless discharge lamp,HFED for short,is an up-to-date high tech prod uct integrated with applied optics,power electronics,plasma study,magnetic material study and the like disciplines.As a new type light source representing future development trend,it is of high luminous efficacy,high color rendering property and long service life,destined to become the most promising energy-saving and environ mental-protection light source in the 21st century。
Structure and Operating Principle of Electrodeless Lamp:
The HFED comsists of bulb,power coupler and high-frequency generator.The power coupler is built inside the bulb,connecting the high-frequency generator through feeder line.The coupler induces and couples high-frequency electromagnetic enerGP created by the generator into the bulb,which makes the air inside the bulb cumulatively ionized into plasma.Excited atom of the plasma whlie returning to ground state will spontaneously radiate ultraviolet light that will invigorate the phosphor powder on inner wall of the bulb to give off visible light.
Features of HFED
1.Super long service life:
No filament and electrode in the bulb,Service life of the bulb depends on natural attenua tion of phosphor powder.It has the longest service life among all light sources. Designed service life≥60 thousand hours, 50 times that of incandesent lamp ,and 10 times that of gold halog en lamp.
2,High-efficiency & EnerGP-saving:
High luminous efficiency and excellent enerGP saving. The opticiency ≥ 65lm/w,5 times that of ordinary incandescent lamp . Can save enerGP more than 80%.
3.Envionmenttal Protection:
Freedom from filcker, no spluttering and low glare. Can thoroughly eliminate eye fatigue.Free of liquid mercury,it is the best light source for environmental protection.
4.Excellent color Rendering:
Color rendering index ≥ 80, extremely close natural light. Comfortable lighting,Multiple choices of color temperature. Can realize lighting with different color in different environment.
5.Excellent color rendering:
Stating time ≤ 0.5 second.Nos needed ,instant startup.
6,Good Electric Specification:
In line with national standard of electromagnetic compatibility:GB17743-1999.No intergernce to outside world.
7.Strong Expancded Function:
Can realize DC supply,timing open circuit and other personal function design. Fully satisfy diversifide customers' needs.
